DOOR CHECK. APPLICATION F|LED`JAYN.18, 192|.
1,373,646. Patent-,ea Apr. 5,1921.
ENEVOLD BANG @Hoznm UNITED STATES ENEVOLD BANG, 0F MINNEAPOLIS, MINNESOTA.
DOOR-CHECK.
Application filed' January 18, 1921.
To all 'whom 'it may concern Be it known that I, ENEvoLD BANG, a sub-V 'ect of the King of Denmark, residing at inneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Door- Checks, of which the following is a speciflcation.
This invention relates to door checks, and the object is to provide a practical and enicient device for preventing the slamming shut of doors and the resultingnoise. The invention is clearly shown in the accompanyin@ drawing, in which;
,Figure 1 is a horizontal sectional view of a door portion and my improved door check attached thereto, or as seen on the line 11 in Fig. 2. l
Fig. 2 is an enlarged sectional view on the line 2-2 in Fig. 1.
Referring to the drawing by reference numerals, 3 designates a door, which is shown in Fig. 1 as being almost closed in its frame 4:. 'Io the door 3 is secured in horizontal position a sheet metal casing 5 in the outer end of which is secured a cylinder 6 by bolts 7. One end of the casing 5 and the cylinder 6 is closed by an end piece 8, the same having a perforation 9 communicating with the cylinder end. A rubber plunger or piston 10 is provided in the cylinder. Said plunger is widest at its forward end and is at that end also cupped, so that only a comparatively thin edge 11 will contact with the interior surface of the cylinder. The rear end of the plunger 10 is secured in one end of a connecting member 12 by means of a pin 13 and two inwardly punched tongues 111. The other end of the member 12 is pivotally secured at 15 to a bell crank lever ,16 which is mounted on a .bolt 17 To the other arm of the bell crank lever 16 is secured a roller 18 the same heing adapted to coact against the frame t It will thus be apparaent that when the door 3 is quickly shut it will not slam with a loud noise. Instead, the roller 18 will cause the plunger 10 to move forward, compressing the air in the cylinder. Such air will gradually escape through the vent 9 as the door closes. When the door is again opened a vspring 19 is provided which will Specification of Letters Patent.
Patented Apr. 5, 1921.
Serial No. 438,245.
return the plunger 10 to its rearward position, air being admitted to the cylinder through the hole 9. It may be observed air may also pass around the thin edges 11 of the plunger when the latter is drawn backware.
It is understood that suitablefmodiczu tions may be made in the form and structure of this invention if such modifications come within the spirit and scope of the appended claims.
Having now therefore fully shown and described my invention, what I claim to be new and desire to protect by Letters Patent is:
1. A door check consisting of a cylinder adapted to be secured to a door, a plunger slidably mounted in the cylinder, a pivotally mounted bell crank lever having one arm operatively connected with said plunger, and a roller mounted on the other arm of said bell crank lever, said roller being adapted to co-act with the door frame.
2. A door check consisting of a cylinder adapted to be secured to a door, a plunger slidably mounted in the cylinder, said plunger being cupped at its forward end, a suit ably mounted bell crank lever having one arm operatively connected with said plunger, and a roller mounted on the other arm of said bell crank lever, said roller being adapted to co-act with the door frame.
3. A door check consisting of a cylinder adapted to be secured to a door, a plunger slidably mounted in the cylinder, spring means for retaining the plunger in rearward position, a suitably mounted bell crank lever having one arm operatively connected with said plunger, and a roller mounted on the other arm of said bell crank lever.
4. A door check consisting of a cylinder adapted to be secured to a door, an end wall. closing the front end of saidcylinder, said end wall having a perforation therein, a plunger slidably mounted in the cylinder, a suitably mounted bell crank lever having one arm operatively connected with said plunger, and a roller mounted on the other arm of said bell crank lever.
In testimony whereof I affix my signature.
